Stage 0 (Emulation of Stock) Map Stronger than Stage 1?

[CA_MS3]

I installed an Accessport v3 on my 2011 Mazdaspeed 3 last weekend. The car has 65k miles, has been well-maintained, and is in essentially stock configuration. The only engine modification is a Cobb cat-back exhaust. I loaded the Stage 1 map and was shocked to find a substantial reduction in mid-range torque, from roughly 2700 to 4500rpm. It almost felt like a safe mode, but no trouble codes were thrown. I drove it for a week like this, figuring the ECU might “learn” and improve, but it did not. Loading the Stage 0 map yesterday brought back the power and seemed to resolve the issue.

Does this seem like a normal response for a stock car?
Has anyone else experienced something like this?

Yes. Cobb's off-the-shelf maps are atrocious, neutered, and calibrated to try and be "safe" on any car to which they're installed. You need a tune customized for your modifications by a professional tuner.

Thanks, I appreciate the feedback.

you may datalog both tune and compare data to see what is going on. You may post it here and we will take a look...

As stated above these tunes are not the best but did you make sure you got the proper one based on what is listed from Cobb website?

I don't know all details about them but if you flash a tune made for a slightly larger intake and still have the oem, it may read higher load values and choke your car power a bit....

Back in time, i remember the biggest change i did notice with stage 1 was removing the boost limit of first and second gears without much feeling of power gains but it was 10 years ago lol.....
